Respect your soul: don't keep repeating "I'm going to make it". Your soul already knows that, what it needs is to use the long journey to be able to grow, stretch along the horizon, touch the sky. An obsession does not help you at all to reach your objective, and even ends up taking the pleasure out of the climb. But pay attention: also, don't keep saying "it's harder than I thought", because that will make you lose your inner strength.
Everything new troubles us. Life catches us unawares and obliges us to journey towards the unknown, even when we do not want to, even when we do not need to.
Harmony sinks deep into the recesses of the soul and takes its strongest hold there, bringing grace also to the body & mind as well. Music is a moral law. It gives a soul to the universe, wings to the mind, flight to the imagination, a charm to sadness, and life to everything. It is the essence of order.
If everything is made up of little particles and all the little particles follow quantum mechanics, then shouldn't everything just follow quantum mechanics?
